There is a true joke that, in the recent history of the Catholic-vs-Protestant struggles in Ireland, an atheist was stopped at a street blockade. He was asked to identify himself as either a Catholic or a Protestant. He said he was an atheist. After a pause, the guard asked "a Catholic atheist or a Protestant atheist?"
While being amusing (and sad...really...Ireland's history is so fucked up) and a true incident, there is an interesting aspect to this joke. Where we come from contributes so much to who we are today and where we're going. An atheist who was raised Catholic would emphasize different thing than a Protest-atheist or a Hindu-atheist.
I believe that thinking in this same way in relation to gender should be discussed more. So far, the only time I've heard/read this line of thinking in relation to gender happen only at the Womyn's Music Festival "you're transgendered, I knew that I felt MALE ENERGY emanating from you!" The politics of that bullshit aside, there is something to that "male energy" that hasn't been explored (to my knowledge) probably because it reeks of stupidity so much.
One's gender, expression, etc. says a lot about one's background. An Earth Mother-type feminine person probably has a different history than a dominatrix-type feminine person and so on. It's not an "energy" but more of a way a person emphasizes different aspects. And that says a lot about one's background.
I've noticed that, maybe 70% of the time, I'm attracted to androgynous people with a feminine (imposed by oneself, by others, or just natural) background; this is probably because it lines up with my imposed-feminine background that leads to my androgynous exploration today. In some ways, the approach is more significant than the effect.
I hope to see/hear/read this kind of discussion sometime in the future in queer circles...even if I'm the one to instigate it.
